1. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

2. A nurse is reviewing the plan of care for a client who is receiving chemotherapy for cancer. Which of the following interventions should the nurse include to prevent infection?

• A. Encourage the client to eat high-protein foods
• B. Encourage the client to drink 2 liters of fluid daily
• C. Instruct the client to use a soft toothbrush
• D. Instruct the client to use a mouthwash containing alcohol

Correct answer: C

Rationale: The correct answer is to instruct the client to use a soft toothbrush. Using a soft toothbrush helps prevent bleeding in clients receiving chemotherapy, who are at risk for mucositis. Encouraging the client to eat high-protein foods (Choice A) is important for overall health but not directly related to preventing infection. Encouraging the client to drink 2 liters of fluid daily (Choice B) is essential for hydration but does not specifically prevent infection. Instructing the client to use a mouthwash containing alcohol (Choice D) is contraindicated as alcohol-containing mouthwashes can cause irritation and dryness in the oral mucosa, increasing the risk of infection.

3. What are the key differences between viral and bacterial infections?

• A. Viral infections typically last longer than bacterial infections.
• B. Bacterial infections typically cause high fever.
• C. Both bacterial and viral infections cause rashes.
• D. Viral infections cause sudden onset of symptoms.

Correct answer: A

Rationale: The correct answer is A. Viral infections typically last longer than bacterial infections. This is because viral infections often require the body's immune system to fight off the virus, leading to a longer duration of illness. Bacterial infections, on the other hand, often cause a rapid onset of symptoms due to the toxins produced by bacteria. Choice B is incorrect because not all bacterial infections cause high fever. Choice C is incorrect because rashes can be caused by both bacterial and viral infections, but not always. Choice D is incorrect because while some viral infections may cause a sudden onset of symptoms, it is not a key distinguishing factor between viral and bacterial infections.

4. What are the early signs of hypoglycemia in a diabetic patient?

• A. Sweating and trembling
• B. Confusion and irritability
• C. Dizziness and increased heart rate
• D. Nausea and vomiting

Correct answer: A

Rationale: The correct answer is A: 'Sweating and trembling.' These are classic early signs of hypoglycemia in a diabetic patient. Sweating occurs due to the activation of the sympathetic nervous system in response to low blood sugar levels, while trembling is a result of the body's attempt to increase muscle activity to raise blood sugar levels. Confusion and irritability (Choice B) are more advanced signs of hypoglycemia that occur if the condition is not treated promptly. Dizziness and increased heart rate (Choice C) can also occur but are not as specific and early as sweating and trembling. Nausea and vomiting (Choice D) are more commonly associated with other conditions or severe hypoglycemia, rather than being early signs.

5. Which intervention is most important for a client with chronic heart failure?

• A. Encourage fluid intake to prevent dehydration
• B. Monitor the client's weight daily to assess fluid balance
• C. Limit sodium intake to reduce fluid retention
• D. Restrict daily activity to prevent fatigue

Correct answer: B

Rationale: The correct answer is to monitor the client's weight daily to assess fluid balance in clients with chronic heart failure. Monitoring weight helps in detecting fluid retention or fluid loss, which is crucial in managing heart failure. Encouraging fluid intake to prevent dehydration (choice A) may worsen fluid overload in heart failure patients. Limiting sodium intake (choice C) is essential but not the most important intervention compared to monitoring weight. Restricting daily activity (choice D) is not recommended as it is important for clients with heart failure to engage in appropriate levels of physical activity to maintain their overall health.
